Integrin alpha 4, also known as CD49d, is a transmembrane protein that forms heterodimers with beta 1 or beta 7 integrins. These complexes contribute to the trafficking of many hematopoietic cell types. Integrins alpha 4 beta 1 (also known as VLA-4) and alpha 4 beta 7 (LPAM-1) are receptors for fibronectin, VCAM and MAdCAM-1.
